BACKGROUND OF THE INVENTION

1. Technical Field

The present invention relates to a transporting bag structure, and moreparticularly to a transporting bag structure capable of transportingliving organisms.

2. Related Art

Currently, numerous appliances for transporting goods are commerciallyavailable, but not all the appliances may be used to transport livingorganisms. For example, currently, live fish are generally transportedby using containers such as rigid plastic trays or buckets. However,during transportation, in the event of a long route or an uneven road,water in a rigid plastic tray or a bucket easily overflows due to fierceshaking under the influence of the uneven road.

Furthermore, when a transportation route is too long and especially whenthe journey lasts more than two or three days, the fish in the containerusually die from lack of oxygen. Therefore, if a conventionalaccommodating object such as a rigid plastic tray or a bucket is used asthe container for transporting live fish, the fish are very likely todie during the transportation, resulting in financial loss. When thelive fish reach the transportation destination, containers such as arigid plastic tray or the bucket for containing the live fish and thewater are not easily recycled, and occupy space. Consequently, thetransportation manner even involves the concept of environmentalprotection.

In addition, also water is directly filled in a water bag and a rope istied at the opening of the water bag to prevent water from overflowingfrom the opening. However, after the water bag is transported to thedestination, the tied rope still needs to be untied to fetch thetransported, live fish, which is time-consuming and troublesome.

SUMMARY

Accordingly, the present invention provides a transporting bagstructure, which includes: a bag body, including an opening and anaccommodating space; and a channel pipe, located at the opening andconnecting the accommodating space and an outside space. The channelpipe includes a first end and a second end. The first end is exposed outof the bag body and located at the outside space. The second end islocated inside the accommodating space. A gas and a fluid flow into theaccommodating space via the channel pipe to form a gas layer and a fluidlayer. The channel pipe penetrates the gas layer and has the second endimmersed in the fluid layer. The channel pipe is closed being pressed ina segmented manner because of different pressures on the layers, so thatthe gas of the gas layer is not able to flow back out of theaccommodating space via the channel pipe, and the fluid of the fluidlayer is also not able to flow back. The channel pipe is closed due tothe pressure generated in the gas layer, so that the gas of the gaslayer is not able to flow back out of the accommodating space via thechannel pipe.

Furthermore, the bag body of the present invention is formed by bindinga first plastic membrane through heat-sealing. A heat-resisting materialis coated on a part at the heat-sealed binding of the bag body, and thepart is not bound during the heat-sealing to form the opening. Inaddition, the channel pipe is formed by binding corresponding sides oftwo stacked second plastic membranes through the heat-sealing. Thechannel pipe is bound to the opening through the heat-sealing, and aninside surface of the channel pipe is coated with a heat-resistingmaterial in advance, so that during the heat-sealing, the opening andthe channel pipe are bound through the heat-sealing, and the insidesurface of the channel pipe is not bound, connecting the accommodatingspace and the outside space. The accommodating space contains more thantwo fluids and gases with different densities. The gas having a smallerdensity is not capable of penetrating the fluid having a larger density,so the channel pipe is pressed by the different fluid pressure and gaspressure respectively in the bag body to form inlet and channel lock, sothat a liquid in the bag body is not able to flow back. The differentpressures are formed between the fluid and gas, so the second plasticmembranes are tightly attached to form gas lock.

According to the present invention, the second plastic membranes areheat-sealed to form the channel pipe and the bag body, and the fluid andthe gas flow into the bag body from the outside via the channel pipe.When the channel pipe is immersed in the fluid in the bag, the gas risesbecause of the small density to form a gas pressure space, so an uppersegment of the channel pipe is pressed by the gas, so that the secondplastic membranes are tightly attached to each other to form lock.Furthermore, a lower segment of the channel pipe is immersed in thefluid in the bag, and the second plastic membranes are pressed by thefluid pressure, so that the second plastic membranes are tightlyattached to each other to form lock. As a result, the gas in the bag isnot able to flow back via a channel outlet immersed in the liquid.Furthermore, although the liquid in the bag contacts the channel outlet,the channel lock generated by the gas pressure of the upper segment isnot capable of being opened because of high specific gravity of theliquid, so the liquid is not able to flow back, and furthermore, waterand oxygen exchange occurs due to shaking during transportation to keepoxygen in the liquid, so the problem of lack of oxygen or water loss inthe conventional process of transportation can be solved.

DETAILED DESCRIPTION

FIG. 1 is an integral outside view of a transporting bag structureaccording to the present invention, which includes a bag body 10 and achannel pipe 20.

FIG. 2 is a structural outside view of the bag body according to thepresent invention. Please refer to FIG. 2, the bag body 10 maypreferably be a sealed bag body formed of first plastic membranes 11.The bag body 10 having an accommodating space 12 is formed by firstfolding the first plastic membranes 11 so that the first plasticmembranes 11 are folded with each other, and then binding sideperipheries of the first plastic membranes 11 folded with each otherthrough heat-sealed binding. With this as a foundation, a heat-resistingmaterial (not shown), is coated at the heat-sealed binding of the sideperipheries of the first plastic membranes 11. During the heat-sealing,the side peripheries of the first plastic membranes 11 are heat-sealedto form a gas tight state, and a part coated with the heat-resistingmaterial is not bound, so an opening 13 is formed here. The bag body 10is preferably a cubic shape, but the present invention is not limitedthereto.

FIG. 3 is a structural outside view of the channel pipe according to thepresent invention. Please refer to FIG. 3, the channel pipe 20 is formedby binding two stacked second plastic membranes 21 through theheat-sealing. Preferably, a connected gas channel is formed by bindingtwo corresponding sides 21 a of the second plastic membranes 21 throughthe heat-sealing and other areas are not bound to each other.

FIG. 4 is a combination diagram of the bag body and the channel pipeaccording to the present invention. Please refer to FIG. 4, in which thechannel pipe 20 is bound to the opening 13 (as shown in FIG. 2). Apreferred binding manner is heat-sealed binding, but the presentinvention is not limited thereto. On this basis, an inside surface ofthe channel pipe 20 may be coated with the heat-resisting material 22 inadvance, so when the bag body 10 and the channel pipe 20 are being boundthrough the heat-sealing, since the inside surface of the channel pipe20 is coated with the heat-resisting material 22, the inside surface ofthe channel pipe 20 is not bound during the heat-sealing, and thechannel pipe 20 stays in a connected state.

Furthermore, the channel pipe 20 further includes a first end 23 and asecond end 24. When the channel pipe 20 is bound to the bag body 10through the heat-sealing, the first end 23 is exposed out of the bagbody 10 and located at an outside space. The second end 24 is locatedinside the accommodating space 12 of the bag body 10. Through thedisposition of the channel pipe 20, the accommodating space 12 and theoutside space can be connected.

FIG. 5 is a use diagram of filling a gas and a fluid in the bag bodyaccording to the present invention. Please refer to FIG. 5, which showsa user may input the fluid, for example, water or other liquids, and thegas, for example, oxygen, into the accommodating space 12 through theconnection of the channel pipe 20 to form a gas layer 30 and a fluidlayer 40. On this basis, when the fluid is filled in the accommodatingspace 12, the second end 24 of the channel pipe 20 is located inside theaccommodating space 12, penetrates the gas layer 30, and is immersed inthe fluid layer 40. Furthermore, the bag body 10 further has an outletportion 14 located at one side of the bag body 10 and used fordischarging the fluid in the accommodating space 12. The first plasticmembranes 11 may preferably be melted in advance in preparation for theoutlet portion 14 so the outlet portion 14 is a generally conduit-likestructure and the outlet portion 14 then becomes gas tight throughheat-sealing.

Furthermore, the second end 24 of the channel pipe 20 of the presentinvention further has a weight element 25, and a preferred dispositionposition is a tail end of the second end 24 of the channel pipe 20.Through disposition of the weight element 25, the second end 24 of thechannel pipe 20 is more easily immersed in the fluid layer 40. Theweight element 25 may preferably be a number of multi-sheet bodies orother metal sheets, but the present invention is not limited thereto.

FIG. 6 is an outside view according to a second embodiment of thepresent invention. Please refer to FIG. 6, in which in addition to acubic structure as described above, a transporting bag structure of thepresent invention may have other shapes. As shown in FIG. 6, a sideopposite to the side connected to a channel pipe 20 has a sealed flatshape, and the other two sides are sealed to form a generally ovalstereoscopic structure. However, a shape of a bag body 10 is only anexample, and the present invention is not limited thereto.

When a user uses the transporting bag structure of the presentinvention, water and living organisms, for example, fish, to betransported are injected into an accommodating space 12 of the bag body10 through the channel pipe 20. When a water level reaches a certainpoint, that is, a tail end of a second end 24 of the channel pipe 20 isimmersed in a fluid layer 40, a gas, for example, oxygen, is theninjected into the accommodating space 12 of the bag body 10 via thechannel pipe 20. At this time, the tail end of the second end 24 of thechannel pipe 20 is extruded under a fluid pressure of the fluid layer40, so two second plastic membranes 21 are tightly attached to eachother to form gas lock, so that a fluid of the fluid layer 40 cannotflow back out of the accommodating space 12 via the channel pipe 20. Onthis basis, the gas also cannot permeate the fluid to flow back out ofthe accommodating space 12 from the channel pipe 20. After use, anoutlet portion 14 may be cut, so that the fluid flows out via the outletportion 14.

According to the present invention, the channel pipe is bound to the bagbody through the heat-sealing, the fluid and the gas may flow into thebag body via the channel pipe, and the channel pipe is formed of the twosecond plastic membranes. Therefore, when the channel pipe is immersedin the fluid, the pressure of the fluid presses the second plasticmembranes, so that the second plastic membranes are tightly attached toeach other to form gas lock. The gas layer on the fluid also tightlypresses the channel pipe in the layer, so that the segment of thechannel pipe is closed to form gas lock. The problem of lack of oxygenor water loss in the prior art is thus solved. After the fish aretransported to the destination, the sealed bag body may be cut to fetchthe fish, and the sealed bag body becomes two membranes, which do notoccupy space and can also be recycled in order to meet environmentalprotection aims, and the transportation cost can also be reducedeffectively at the same time.
